Sir How did you find For mode-1 , T1=0.282sec, Mode-2 T2=0.065sec, T3=0.059Sec. Please sir kindly explain.

1. We scale up the base shear obtained by Response Spectrum Analysis (RSA) to that of the Equivalent Lateral Force (ELF) method. But when RSA base shear is higher than ELF method, why don't we scale down RSA to the ELF ?? 2. Response acceleration should be zero at T = 0 in response spectrum curve. But response acceleration is starting at coordinate equal to 40% of SDS (by formula). Why is it so ??

I passed CA seismic exam on my first go. Walked away feeling like I didn't have a good grasp on the topic. You did in 15 minutes what I couldn't learn in 100 hours of studying. Thank you.

Hi Dr Nafie, how did you obtain the mode shape? I would like to obtain a simple expression for idealizing a building as a prismatic member, I think it can be done, but the hardest trick is the mode shape. And, deflection of the tip of the building I think can also be obtained from the modal participation multiplied by acceleration multiplied by mode shape.

Undoubtedly great video, thank you. Constructive criticism from a non-engineer (and general advice to presenters of all kinds): Give the point of the slide at the beginning instead of the end
